gibbous margin. Inner spine of palpal organs similar, but 
shorter, its point falling well away from and above the outer 
spine; the basal stalk of this spine with only a slight blunt 
lobe anteriorly (not a sharp point). Apex of mandible with a 
much longer and more slender spur above -

third of the upper margin, situated on an almost tuberculiform 
gibbosity. 
(Tibia of palpus nearly four times longer than broad. Inner 
spine of the palpal organs long, stout, straight, slightly 
curved at the apex, outer spine deeply bifid at the apex, 
its basal portion with two large, sharp, curving spurs.) . {

tooth above, a larger one below. Mandibles and fang much 
less strongly developed than in any of the above species. 
a. Inner spine of palpal bulb almost straight . . . . . . . remotus, Peckh. 
b. Inner spine of palpal bulb strongly curved outwards over the

I]. Tibia and protarsus 1. without any decided fringe on each side; apex 
of leg-segments dark. (Tibia of palpus four times longer than broad, 
without a distinct pencil of bristles, but with a few more or less 
scattered ones only on the upper margin, which is not gibbous. 
Inner spine of bulb stout and curved outwards towards the apex. 
Mandibles immensely stout ; fang deeply sinuous, forming a large 
semicircular lobe at its base; apical tooth on the lower side deeply 
bifid, the tooth on the upperside strongly developed.) . . . . . mandibulatus, sp. n. 
Females. 
A. Vulva presenting a pair of large circular, circular-oval, or elliptical 
discs, lying just beneath the surface of the epidermis. 
i. Size larger, length 9 millim. Vulva with two large circular-oval 
discs two diameters apart. 
(Between and behind them on the posterior margin is a triangular 
white prominence, flanked on each side by a dark brown 
sinuous spur. Between the discs appear a pair of dark spots 
and in front of them another pair of sinuous spots, both 
marking where portions of the oviduct approach the 
surface.) . . . . . . . . oe . spinifer. 
ii. Size smaller, length 6-7 millim. Vulva with two circular or ellip- 
soidal discs adjacent or less than one diameter apart. 
a. Discs circular, half a diameter apart, close to the posterior margin, 
with a dark transverse curved bar embracing them in front . . elegans, sp. n.
